Experience of Cyclostratigraphic Analysis of Petromagnetic Data on the Turonian–Maastrihtian Section «Nizhnyaya Bannovka» (Volga River Right Bank, Southern Saratov Region)

On the base of spectral Fourier analysis of magnetic susceptibility time series of nearly 10 000 measurements of rock samples in the turonian-maastrihtian sediments, exposed near Nizhnyaya Bannovka village (Volga River Right Bank, Southern Saratov Region) there were detected long and short eccentricity cycles. Petromagnetic variations, correlated with different variants of eustatic curves detected the presence of well known sequences.
